Though it doesn't play a major part in the story, in episode 6, Camille meets up with old friends (one of which is pregnant) and pregnancy is discussed.
Episode 2: A cop is removing a tooth from a pig head. Episode 3: Kids are running after a pig, but they are not killing it becouse a cop is busting them
there are lots of mentions throughout the whole book and it often is descriped in a very gross way (in my opinion). still you can always just skip those passages :)
